Recently several efficient schemes are proposed to provide security of e-medicine systems. Almost all of these schemes have tried to achieve the highest security level in transmission of patients’ medical information to medical institutions through a heterogeneous network like Internet. In this paper, we explain the insecurity of these schemes against(More)
The FPGA (re)configuration is a time-consuming process and a bottleneck in FPGA-based Run-Time Reconfigurable (RTR) systems. In this paper, we present a High Level Synthesis (HLS) method, based on the data path merging technique to amortize the hardware configuration time in RTR systems. It merges the Data Flow Graphs (DFGs) of two or more computational(More)
We propose QTRU, a probabilistic and multi-dimensional public key cryptosystem based on the NTRU public key cryptosystem using quaternion algebra. QTRU encrypts four data vectors in each encryption session and the only other major difference between NTRU and QTRU is that the underlying algebraic structure has been changed to a non-commutative algebraic(More)
A B S T R A C T Elliptic Curve Cryptosystems (ECC) have recently received significant attention by researchers due to their high performance such as low computational cost and small key size. In this paper a novel untraceable blind signature scheme is presented. Since the security of proposed method is based on difficulty of solving discrete logarithm over(More)
High latencies in FPGA reconfiguration are known as a major overhead in run-time reconfigurable systems. This overhead can be reduced by merging multiple data flow graphs representing different kernels of the original program into a single (merged) datapath that will be configured less often compared to the separate datapaths scenario. However, the(More)
